I'll have a transit at HKIA (Hong Kong International Airport) for about 16 hours (all evening / night hours). Will arrive at HK in the evening and fly out the next morning. I don't plan to leave the airport due to hassle of checking out / in and clearing security. So, likely, won't stay at the hotel near the airport (assuming I have to leave the airport terminal). I was wondering if anyone tried the lounges - any comments (yay or nay)? Seems like there are a few options at HKIA: 1) Relaxation Room 2) Resting Lounges (free?) 3) Pay-In Lounges Any comments / recommendations - safety / privacy, etc appreciated Thanks!
